[SR-Users] Re: Skip/discard branch in branch route?

[Yuriy G]

The branch RURI is quite clear I suppose but
For the NAT solving you should pass received set into
$(branch(dst_uri)[-1])  or $du for main brach
Send socket also can be set via $(branch(send_socket)[-1])  or $fs
respectively.

TCP can create new transactions, as UA can wait for incoming requests on
different ports, which is announced in the Contact Header,
However, you may try to use the tcp_keepalive_enable() and tcp_set_alias()
functions when a TCP connection is established to mediate over it if UA
supports this way of interaction.

Hi Yuriy

This looks promising. I was able to set $ru and then add branches to
only send the calls from the registrar with a valid socket.

But I fear: append_branch($(ulc(aor=>addr)[$var(i)])) is not correct
in NAT situation.

aor=>received is probably the one to use, but does not contain the
username part. And also I probably lost that full NAT automation.

I also observed that the sending socket is not preserved. In my case I
have to tcp sockets: 8080 where I run the xhttp api, not used for sip,
and 5060. The outgoing call originates from 8080. So it is definitely
not reusing the existing TCP connection.

Do I have to set $fs? But how do I set this only for a specific branch?
Assume I have multiple contacts, some using TCP other UDP or TLS.

Thank you, I think you pointed me in the right direction.

So going to replace:

if (lookup("location", "$var(lookupuri)")) {

by

if (reg_fetch_contacts("location", "$var(lookupuri)", "aor")) {

Then iterate the contacts and only add the ones having a socket set.

[Yuriy G]

In your case, I would use
https://www.kamailio.org/docs/modules/5.6.x/modules/registrar#registrar.f.reg_fetch_contacts
See example:
https://www.kamailio.org/docs/modules/5.6.x/modules/registrar#idm871

You can iterate over it
Then for the first entry, you can set $ru and $du variables and it will
become the main branch
For the other do append_branch and set parameters of the branch[-1]
accordingly.
So you can control branch creation instead of automatically doing it by
Kamailio and filter all needed.

Nah, just tested, both contain the same branch...

I discovered $branch(send_socket)...

Still not understanding, why I clearly have 4 contacts registerd on the
AOR but only finding 3 of them when looping through the branches but
when route(RELAY) is called, all 4 get traffic.

Hi Yuriy

Not sure if I understood that correctly...

while in request route... the four URI of the branches are:

$branch(uri)
$(branch(uri)[0])
$(branch(uri)[1])
$(branch(uri)[2])

and $branch(count) is 3 because there are 3 'additional' branches?

How do I geht the sockets of those four branches?

$branch(uri)  => $(ulc(aor=>socket)[0])
$(branch(uri)[0]) => $(ulc(aor=>socket)[1])

and so on? Indexes offset by 1?

And, what happens if I set:

$branch(uri) = $null
will $(branch(uri)[0]) become $branch(uri) and eveything shift one
index down?

Main request is the first branch.
So consider changed $ru after lookup as the first (0) branch.
Other branches will be appended as addition.

Hi Yuriy

> server which handles the particular connection.

I have started trying to solve this in request route.

I'm still truggling on how to distinguish local and non local
registrations.

I have 4 CPE registered to the same AOR.

kamclt ul show [AOR] does show they are registered. 3 on the local
registrar (with a socket) and one with socket [not set].

If I repeat on the other registrar I get matching information. One with
a socket, the other three are [not set].

So trying to understand the hard way, what happens:

$var(i)=0;
while($var(i)<=$branch(count))
{
$var(socket) = $(ulc(aor=>socket)[$var(i)]);
xlog("L_INFO", "$cfg(route): DEBUG BEFORE: IDX: $var(i) TOTAL: 
$branch(count) URI: $(branch(uri)[$var(i)]) Socket: $var(socket)\n");
$var(i) = $var(i) + 1;
}

$var(i)=0;
while($var(i)<=$branch(count))
{
$var(socket) = $(ulc(aor=>socket)[$var(i)]);
xlog("L_INFO", "$cfg(route): DEBUG REMOVE: IDX: $var(i) TOTAL: 
$branch(count) URI: $(branch(uri)[$var(i)]) Socket: $var(socket)\n");
if ($var(socket) == 0) {
xlog("L_INFO", "$cfg(route): Dropping Branch IDX 
$var(i) URI: $(branch(uri)[$var(i)]) Socket: $var(socket)\n");
$(branch(uri)[$var(i)]) = $null;
} else {
$var(i) = $var(i) + 1; # do NOT increment index as the 
branches got renumbered.
}
}

$var(i)=0;
while($var(i)<=$branch(count))
{
$var(socket) = $(ulc(aor=>socket)[$var(i)]);
xlog("L_INFO", "$cfg(route): DEBUG AFTER: IDX: $var(i) TOTAL: 
$branch(count) URI: $(branch(uri)[$var(i)]) Socket: $var(socket)\n");
$var(i) = $var(i) + 1;
}

What I did not yet understand.

$branch(count) is 3 !

So, does kamailio only consider the 3 registrations WITH a socket?
Or is this the index starting with 0, thus 4 contacts?

When I do $(branch(uri)[$var(i)]) = $null; then $branch(count) is decremented. 
I suppose because the next contact takes that index, this is why I do NOT 
increment $var(i).

But I then get no $(branch(uri)[$var(i)]) on the highest index, suggesting that 
I only see 3 contacts, not all 4 of them.

Indeed, my 'BEFORE' loop did not output the contact registered on the other 
registrar.

So WHY is there still the INVITE being sent to the fourth, non local contact?

=> Confused!

You also can filter it in the request route and not create branch wich
doesn't belong this server ( you can achieve that by verifying ucl variable
details), or making it UDP branch being forwarded to proper server which
handles the particular connection.

Hi

https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#branch_name_-_branch_attributes

Assigning $null to uri attribute will drop the branch, for the rest of
attributes will just set the value to null.

I fear this does not work within branch_route

if ($var(socket) == 0) {
if ($avp(debug) > 0) {
xlog("L_INFO", "$cfg(route): 
$(branch(uri)[$T_branch_idx]) via Socket: $var(socket) is NOT LOCAL to this 
Registrar - dropping!\n");
}
$(branch(uri)[$T_branch_idx]) = $null;
}

Result:

* Call is still branched to CPE
* $(branch(uri)[$T_branch_idx]) is null on all subsequent branches after the 
first one.

[SR-Users] Skip/discard branch in branch route?

[Benoît Panizzon]

Hi all

Is there a way to skip a branch in branch route?

Situation: Two registrar server with DMQ synced location database.

CPE register via TCP or TLS. To properly work, message have to be sent
over the existing TCP connection.

Multiple CPE register to one AOR.

CPE1 and CPE2 register to Registrar 1
CPE3 registers to Registrar 2

On Registrar 1 there is an established TCP connection to CPE1 and CPE2
but not to CPE3.

Within the Branch Route to the CPE I can check if there is a TCP
as the Branch Route is executed for every contact in that AOR:

branch_route[BR_TO_CPE]
{
[...]
$var(reg_contact_addr) = $(ulc(aor=>addr)[$T_branch_idx]{uri.host});
$var(socket) = $(ulc(aor=>socket)[$T_branch_idx]);
if ($var(socket) == 0) {
xlog("L_ERROR", "$cfg(route): No Socket for: 
$var(reg_contact_addr)");
}
[...]
}

This log an error if the socket is not present on the local registrar.
But is there a way to tell kamailio to skip/discard that contact?

My intention is to parallel branch from the core to both registrars,
that way all contacts would still get the call but via established
TCP socket (and in case of UDP and NAT via correct know ip for ALG 
port-forwarding).

[SR-Users] Re: uac_replace_to() without RR params

[Henning Westerholt]

Hello,

if you track the call with the dialog module and then also use the dialog mode 
in the uac module no variables are stored in the SIP messages. The module will 
store the information in dialog variables. If you use a persistent dialog DB 
mode, it will be also saved in the DB and should even be restored at a restart. 
I remember doing some tests some years ago for a project, and also did some 
fixes/extensions in this matter.

Maybe just give it a try.

Cheers,

Henning

I made some more testing and found that calling dlg_manage() before 
uac_replace() and setting restore_dlg param with value “1” solves my issue and 
doesn’t add params to Record-Route.

In the event of a restart to Kamailio i would like to keep the state of the 
call and not lose the values on the dialog vars where original To and From 
headers are stored. In order to do that i thought of saving the original values 
on a data structure and assigning its value to the lost dialog vars. In order  
to that i need to be able to access those dialog variables. Is that possible? 
What is their name?

Cheers
